NAME

TUI::Gadgets::EventViewer - terminal window for displaying received events

HIERARCHY

TObject
  TView
    TGroup
      TWindow
        TEventViewer

SYNOPSIS

use TUI::Gadgets;

my $viewer = new_TEventViewer(
  $bounds,
  $bufSize
);

$deskTop->insert($viewer);

DESCRIPTION

TEventViewer implements a terminal-style window that displays the attributes of TEvent objects received by the application.

The window captures incoming events and renders them in textual form, allowing developers to observe and debug event flow during program execution. It is intended as a diagnostic gadget and is typically used during development or testing.

The implementation is inspired by the Turbo Vision C++ event viewer and by the TTYWindow concept.
